ELECTRIC RECEPTACLE FOR'FLASHING-POWDER IN FLASH-LIGHT BURNERS.

SPECIFGATION formingpart of Letters Patent No. 555,332, dated February 25, 1896.

,- Application filed January 7, 1895.

.To a-ZZ whom/ t may concern.-

e itl-nom that we, HENRY E. RATHBUN and FREDEREGK BEBBY, citizens of the United States, residing at Pawtucket,` in the State of Rhode island, have invented a new and useul improvement in Electric Flash-Light Cartridges for Photographic Purposes, of which the following is a specification.

The object of our invention is to provide improved means for rapidly producing a hash-light for photographic purposes; 'and it consists in a cartridge made .of perishable materials for holding the dashing-powder, in combination witlna contained electric conductor for igniting the powder, as hereinafter fully set forth.

in the accompanying drawings, Figure 1 tric ashflight cartridge when placed upon the conducting-wires to forni aportion of the electric circuit. Fig. 2 represents an edge view of the cartridge, also showing a transverse section of the electric conducting-wires. Fig. 3 represents a view of the under side of the electric cartridge. Eig. 4 represents an axial section of the cartridge, taken in the line e 4 of Fig. 3. Fig. 5 represents anaxial section of the electric cartridge without the cover and the charge of powder. V

in the drawings,A represents the cartridge,

cheap perishable material, and B is a cap or cover of similar material., which with the part A forms the closed chamber a for holding the flashing-powder C. The under side, b, of the cartridge A is preferably provided with the groove c, adapted to receive the parallel conducting-wires D D', as shown in Fig. 2; but the said groove is not essential and may be dispensed with. .The cartridge A is provided with the perforations d d, (shown in the section Fig. 4,) the said perforations being adapted to receive the line conducting- Vhen the electric cartridge so formed is serrano. 534,119. or@ model.)

Wire E which comes in contactV with the poW- 45 der C at the bottom of the chamber a, the said wire E .being arranged transversely of the groov'e c, so as 'to bear against the sides of the conducting-wires D D', as shown in Fig. 2. -The Wires D D are to be insulated from each other except atjthe connectingwire E, ,so that the electric current in its pas-A sage from one of the'said wires to the other through the wire 4E will cause. the ignition of the charge of powder in the chamber o.

placed upon the wires D D' the shoulders e e the wire E to be held against the outer sides of the wires DD', thus forming an electric connection with the charge of powder-C.

In Fig. 5 the electric cartridge is shown as having the electric connecting-wire E secured thereto, but{ without -the cover B, the said blank cartridge being made of cheap'perish-- able materials to constitute an article of manufacture and sale independent of the flash-light machine kupon which it may be used. i

W'e claim as our inventionl. A blank cartridge for photographic purposes, provided in itself with an electric wire adapted to ignite a charge of dashing powder placed in the cartridge, and with means for attachmentto lthe electric-circuit connections, substantially as described.

2. A cartridge for photographic purposes, provided with an inclosed charge of flashingpowder, and having in itselfan electric wire i adapted to ignite the charge of powder, and

'means for attachment to the electric-circuit 8o connections', substantially as described.
